1. What evidence does Google present for Chinese government censorship? Google says that Chinese customers and advertisers have increasingly been complaining about their Gmail service in the past month. Attempts by users to send messages, mark messages as unread and use other services have generated problems for Gmail customers. Google shows potential signs that the Chinese government is increasing their censorship by revealing that Gmail's e-mailing system features have been disrupted for Gmail users as well as other Gmail interfaces such as sending e-mails. Google also reveals that the users who filed in these complaints are mostly potential threats to the Chinese government such as the activist accounts also with financial, technology, media and chemical companies users' accounts. Thus, even though there is no concrete evidence, there are signs that are most likely to be linked to the Chinese government. 2. How does this impact the Jasmine revolution? The move follows extensive attempts by the Chinese authorities to crack down on the Jasmine revolution, an online dissident movement inspired by events in the Middle East. The censorship was supposed to prevent people from getting too much information but instead, this can provoke people to go against the government since people are aware that they have been treated unfairly. 3. Describe LinkedIn. LinkedIn is a business-oriented social networking site. LinkedIn operates the world's largest professional network on the Internet with more than 100 million members in over 200 countries and territories.

What does it mean to leverage social networks? To leverage social networks, is to use social networks in order to promote their product, such as using it as a tool for advertising. Define digimarketing. Digimarketing basically is marketing, but based and interacted with the social media. Businesses would do advertising, selling products, etc. online for customers that are online. Explain the mistakes marketers make with social networking. Marketers are not using the 'social' side of the social networking sites as an advantage, and just promoting, instead of interacting with their customers. Like for example via Twitter, some marketers try to take advantage of the 'Twitter trend', and promote their product using the words that are trending, so that more people will see, even though their product has nothing to do with the trending word. This may lead to negative comments from users.

An IP address serves two principal functions: host or network interface identification and location addressing. Sources : http://en.wikipedia.org/wiki/IP_address iOS : iOS is Apple's mobile operating system. It was originally developed for the iPhone, and it has extended to support other Apple devices such as the iPod touch, iPad and Apple TV. Geohot : George Hotz, known for working with other people to unlock the iPhone, allowing the phone to be used with other wireless carriers. 5. If possible, describe a solution to the concern (issue).
